TRACK-SANDER.

Specification of Letters Patent.

PatentedFeb. 9, 1915.

Application filed August 5, 1914. Serial No. 855,267.

To all whom it may concern Be it known that I, JOHN H. l/VATTnns, a citizen of the United States, residing at OX- ford, in the county of Calhoun and State of Alabama, have invented a new and useful Track-Sander, of which the following is a specification.

The present invention relates to improvements in track sanders, one object of the invention, being the provision of a track sander, in which the air directing nozzle is so disposed with relation to the sand therewithin, as to force the air into the body of the sand and away from the casting of the sand t 'ap, so that there is no undue wear upon the trap and by means of which the sand will be properly directed out of the dome and trap onto the track.

l/Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of. parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed with out departing from the spirit of the invention.

In the drawingsFigure 1 is a top plan view of the sand trap showing the relative position of the air inlet and sand outlet ports. Fig. 2 is a section taken on line 22 of Fig. 1.

Referring to the drawings, the numeral 1 designates the sand trap, which is of the double type and is provided with the air directing bores 2, one at each end thereof, and the sand directing bores or ports 3 intermediate of the ends thereof. The respective bores 52 and .3 are connected by the chan neled or recessed portions 4 so that sand will be properly delivered to the respective ports 3 and out of the sand directing pipes 5.

Disposed within the lower end of each bore 2 is an exteriorly threaded nozzle memher 6, provided with the air outlet port 7. An air strainer S is disposed within the chambered. portion of the nozzle 7 and is properly held in place by means of the coupling 9 which is in the form of an eX- teriorly threaded bushing, and which carries the air directing pipe 10. It will thus be seen that the air directed through the nozzle 7 concentrically of the bore 2 will be directed upwardly through said bore and into the sand dome (not shown), thus displacing the sand and causing it to be forced out of the bore 3 through the channel 4 or thereabovc from the dome.

From this construction it will be seen that with the air pressure against the sand and directed into the body of the sand instead of against any part of the casting or trap, it will not have a detrimental effect thereon, due to the air pressure forcing the sand in an abrasive manner against the casting. It will thus be seen that the air is so directed into the body of the sand as to prevent undue wear upon the casting or trap.

What is claimed is:

1. A sand trap for track sanders, having i o transversely disposed bores in communi cation with each other, such communicating portion constituting a sand directing means, and an air directing nozzle mounted in the lower end of one of the bores concentricallv thereof. U

2. In a track sander, a sand trap having two transversely disposed bores in communication with a longitudinal channel, and an air directing nozzle mounted in the trap for directing air into the body of the sand, said nozzle having a chamber in its end to permit the air jet to be spread and not blast the sand abrasively against the walls of the trap.

3. A sand trap for track sanders, including a body having two parallel bores in communication with a cross bore, said body being open at one side, one of the transverse bores constituting the sand outlet, a plug disposed in the remaining transverse bore and terminating at a point below the bottom of the connecting bore, said plug being providcd with a chamber and an air jet outlet, and an air pipe coupling mounted in said chamber and terminating at a point to provide a space in the chamber.

In testimony that I claim the foregoing as my own, I have hereto aliixed my signature in the presence of two witnesses JOHN HENRY l/VATTERS.
